A collection of useful materials for dealing with OPAL data extracts
(We assume you're using RStudio.)
Source the opal.R file
Use the console window to set the directory in which the extract you're currently exploring lives.
OPALDATA <<- "~/Downloads/ohc.2015-10-26/"
You can now start using the various utility functions to explore the data - for example:
view_table(demographics)
age_distribution()
common_diagnoses()
common_tests()
